Objectives. This study aimed to compare the oncological outcomes of partial versus superficial or total parotidectomy forsuperficial T1 or T2 primary parotid cancers and investigate their prognostic factors and recurrence patterns. Methods. The medical records of 77 patients with T1–2 primary parotid malignancies between May 2003 and March 2022were retrospectively reviewed. Univariate and multivariate analyses were performed to evaluate the prognostic fac-tors associated with overall survival, disease-free survival, and local and distant recurrence. Results. The average follow-up duration was 70.2 months (range, 12–202 months). The 5-year overall and disease-free sur-vival rates were 88.7% and 77.1%, respectively. Twenty-two patients underwent partial parotidectomy, and 55 un-derwent superficial or total parotidectomy. There were no significant differences in the disease recurrence (P =0.320)and mortality rates (P =0.884) of the partial and superficial or total parotidectomy groups. The mean duration of sur-gery was shorter and the overall complication rates were significantly lower in the partial group than in the superfi-cial or total parotidectomy group (P =0.049). Sixteen cases of recurrence occurred during the study period (20.8%). Univariate analyses showed that high-grade tumors (P =0.006), lymphovascular invasion (P =0.046), and regionallymph node metastasis (P =0.010) were significant risk factors for disease recurrence. Multivariate analysis identifiedregional lymph node metastasis as an independent prognostic factor for disease recurrence (P =0.027), and lympho-vascular invasion as an independent prognostic factor for overall survival (P =0.033). Conclusion. The conservative surgical approach of partial parotidectomy can yield oncological outcomes comparable tothose of superficial or total parotidectomy with careful patient selection in T1-2 parotid cancers.
